y Whenthe pipe is lin uSesmOIie fromp'thebowl 10j through' the portf14into through the port 19 of. mouth piece 18 into It is feature of `idnve'ntion theend Y nicotine whichis vdeposited-uponethe "Wall j ina i ofthe tubular member A which fits telescopically within the stem section11, insteadV of upon the exterior of the latter, serves as a lining orshield to prevent contact of the liquid within the member A with anyconsiderable portion of the interior of the socket 12, the only portionthereof with which the liquid may make contact being the conical boss13. Therefore, neither the lower portion of the bowl 1G or the steinportion V11 thereof becomes wet or saturated with moisture and saidparts are kept dry and, to a considerable degree, prevented fromswelling or expanding. Whenever it is necessary to remove the liquidthat has collected within the intermediate metal member A the endportionV 15 thereof is withdrawn from the socket 12 and the liquidshaken out; .ln this connection it is pointed out that it isadvantageous to arrange the end portion. 15 to telescope vwithin thestem section 11 instead of upon the exterior thereof asin thelatter casel have found that the woodof the stem portion 11 will be 4exposed tosuch an extent to the liquid Y within the member A that the wooden stemportion 11 will become saturated with moisture resulting-in an expansionof the same that binds it so tightly within the metal part as to preventseparation of the bowlfrom the latter. With the constructionand-arrangement described a very small part of the stem portion 11 ofthe bowl is exposed to the liquidwithin the member A, and since the endportion 15 of the metal member A is fitted within said stem portion,swelling or expansion of the Vlatter does not operate to clutch the twoparts together so that they can not be separated. Y

As will be clear from the above description my improved pipe comprisesonly threev es-` sential parts and by constructing the stein of the pipein the manner above set forth the wood ofthe bowl 10, including its stemportion 11, is kept dry and, therefore, cinders or ashes will not adhereto and build up upon the interior of the bowl as heretofore andtheformation of plugs of unburnt wet tobacco at the bottom of the bowl isprevented.

l"Vhile l have herein above referred to the tubular memberA as being`made from sheet metal. it is obvious that glass or any other suitablematerial may be employed for the same. Y.' l Y w That l claim is .Y 'Avsmoking pipe comprising a bowl meinber made adjacent its lower endandnpon its exterior with a socket and having anl outlet conduitcommunicating at its inner end with the interior of' said bowl near thebottoni thereof. and having' its outer end portion constituted in partby an integral tubular extension of said bowlmember centrally disposedwithin said socket and projecting outwardly well beyond the bottom ofthe latter; a single tubular one-piece intermediate stem member that iscircular in cross section of relatively scopically fitted within theouterend of said intermediate stem member.
